The Arizona Diamondbacks saw a productive stretch end in Seattle on Sunday as their offense again failed to provide enough support, suffering a 3-2, 10th‑inning loss that completed a three‑game sweep by the Mariners. The defeat — the third time Arizona has been swept this season — erased momentum the club had carried into T‑Mobile Park and left the Diamondbacks departing the Pacific Northwest on a three‑game skid.
Arizona Diamondbacks batter takes a swing during the series finale — a game in which Arizona’s offense went quiet in the 3-2, 10th-inning loss that completed the sweep by Seattle.
Arizona managed just three hits over the course of the game, leaving starter Merrill Kelly without the run support he needed. Kelly worked 5.1 innings, surrendering two runs on eight hits while recording two strikeouts. Despite his length in the game, the lack of offensive production from the Diamondbacks limited the club’s ability to capitalize on scoring opportunities and ultimately forced the contest into extra innings.
On the other side of the matchup, the Mariners used a tandem approach to cover the regulation innings. Bryce Miller delivered five shutout frames, allowing a single hit and issuing one walk while holding Arizona’s lineup scoreless during his stint. Luis Castillo followed with five innings of his own, yielding two runs (one earned) on two hits and two walks. Together, Miller and Castillo accounted for the 10 innings of work that kept Seattle in position to secure the extra‑inning victory.
Offensively, the Diamondbacks’ only base knocks came from Corbin Carroll, Ildemaro Vargas and Gabriel Moreno, each collecting one hit in the loss. The sparse offensive ledger underscored Arizona’s struggles across the series, with the club unable to generate sustained pressure against Seattle’s pitching staff. Over the three games, one opposing player emerged as a particular thorn: Dominic Canzone, who had entered the series hitting .237 with five homers on the season, finished the matchup a combined 5‑for‑10 with two home runs against Arizona.
The sweep marked a sharp turn for a Diamondbacks squad that arrived in Seattle riding a five‑game winning streak and boasting 10 victories in its previous 11 outings. That run had pushed the team to a season‑best seven games over .500, but the three losses this weekend reversed that short‑term gain and extended the club’s current slide. The back‑to‑back offensive rust over the series — including Sunday’s three‑hit performance — will be an immediate area of focus as the team prepares for its next opponent.
